Download or read book Chondrichthyes written by Luis Fernando Rodrigues-Filho and published by BoD – Books on Demand. This book was released on 2017-12-20 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chondrichthyes are a group of cartilaginous fish, where we have sharks, rays, and chimeras as members. This group plays an important role in aquatic ecology, as they act as predators throughout the food chain (e.g., sharks). However, many populations of Chondrichthyes are threatened by several factors (increased direct fishing, high mortality rate as accompanying fauna, marine pollution, habitat destruction, etc.). These declines are evident in many parts of the world and have come to the attention of scientists, conservation organizations, the media, and the general public. Fisheries legislation regulating international fisheries markets has been amended to provide greater protection for this group along with other species of fish. However, little is known about these species, which reinforces the importance of studies in order to have a better understanding of the elasmobranch stocks, as well as to identify the influences of the anthropic action of fishing. In response to knowledge on the low sustainability of cartilaginous fish fisheries on a global scale, FAO has developed an international plan of action for the management and conservation of these fish, with the aim of developing and implementing national plans of action to ensure management and conservation of these stocks, having as main recommendation the collection of information about the Chondrichthyes, especially the sharks. Even so, this group is little known in terms of biodiversity, ecology, behavior, and a host of other characteristics relevant to this taxon, which is very worrying. Chondrichthyes - Multidisciplinary Approach attempts to portray to the readers up-to-date information on Chondrichthyes to promote an overview of the current taxon, serving as an indispensable source of access to more accurate and detailed information on shark rays and chimeras.
Download or read book Authentication Of Chinese Medicinal Materials By Dna Technology Techniques And Applications Second Edition written by Pang-chui Shaw and published by World Scientific. This book was released on 2022-11-08 with total page 547 pages. Available in PDF, EPUB and Kindle. Book excerpt: For centuries, Chinese medicinal materials have been used for therapeutic purposes. Chinese medicinal materials are traditionally identified by their organoleptic characteristics, such as the texture or the odor. With the advancement of DNA technology, a molecular approach has become an important tool to complement organoleptic, morphological, anatomical and chemical techniques for the authentication and quality assurance of Chinese medicinal materials.In 2002, the authors published Authentication of Chinese Medicinal Materials by DNA Technology which is the first international reference in this field. After 20 years, this new edition updates the various useful techniques and describes the new techniques developed for molecular authentication. The procedures of each DNA technique are provided in detail for 'step-by-step' experiments.This book is divided into 5 parts with 18 chapters. Part I reviews the current status of molecular authentication and introduces a wide range of DNA techniques. Part II lists the experimental procedures for molecular authentication. Part III describes the DNA fingerprinting-based techniques. Part IV describes the DNA sequencing-based techniques. Finally, Part V provides an account on the recent advancement in molecular authentication, including guidelines for setting up a proper DNA laboratory and concluding remarks.
Download or read book A Synthesis of the Gal pagos written by Guillermo Paz-y-Miño-C and published by Cambridge Scholars Publishing. This book was released on 2024-03-08 with total page 619 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are hundreds of books and thousands of scientific articles about the Galápagos. This volume is distinctive. The authors, Guillermo Paz-y-Miño-C and Avelina Espinosa, synthesize, integrate, and conceptualize the most recent evolutionary-biology research being conducted in the archipelago’s terrestrial and aquatic environments; the conflicts resulting from human interactions with nature, including local population growth and tourism practices in the context of short- and long-term conservation efforts; and make predictions about the destiny of the Galápagos’ unique biodiversity and landscapes under various scenarios of climate-change impacts, urbanization trends, diversification of tourism, and conservation investments. Offering over 260 figures and diagrams, this work will appeal to a broad audience, including professors in academia, college instructors, postdoctoral fellows, graduate students, and research undergraduates. Another target audience is study-abroad and international field-trip instructors and their students who travel to the Galápagos year-round. Science writers and policymakers will find in this book useful information to discuss and debate about imminent environmental threats to afflict the Galápagos as a consequence of human population growth, tourism practices, and climate change.
Download or read book Additions to a Revision of the Shark Genus Carcharhinus written by J. A. F. Garrick and published by . This book was released on 1985 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: Features of the valid nominal species of Aprionodon Gill (isodon Valenciennes) and Hypoprion Müller and Henle (hemiodon Valenciennes, macloti Müller and Henle, and signatus Poey), plus those of a previously unrecognized species here described as Carcharhinus leiodon n.sp., are examined and compared with those of Carcharhinus Blainville. Features studied include morphometrics, vertebral numbers and other vertebral characteristics, tooth numbers, color pattern, and some other aspects of external morphology. It is concluded that on these features C. Leiodon n.sp. is entirely encompassed within the parameters of Carcharhinus, and that, although A. isodon, H. hemiodon, H. macloti, and H. signatus each extend the range of diversity of Carcharhinus in one or more features, A. isodon is not uniquely different from Carcharhinus, and there is no common pattern of difference between the three species of Hypoprion and Carcharhinus. Accordingly, and because the nature of the teeth of Aprionodon and Hypoprion has been found insufficient to warrant generic distinction from Carcharhinus, the genera Aprionodon and Hypoprion are synonymised with Carcharhinus. A diagnosis and description are given for each of the above species. The descriptions include measurements, counts, and line illustrations that show the whole shark in lateral view, underside of head, nostril, and teeth. The geographic distribution is summarized, as are also the meager biological data available on number of embryos, size at birth, size at sexual maturity, and maximum size.

Download or read book Coral Reefs of the Gulf written by Bernhard Riegl and published by Springer Science & Business Media. This book was released on 2012-04-13 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coral Reefs of the Gulf: Adaptation to Climatic Extremes is a complete review and reference for scientists, engineers and students concerned with the geology, biology or engineering aspects of coral reefs in the Middle East. It provides for the first time a complete review of both the geology and biology of all extant coral areas in the Gulf, the water body between Iran and the Arabian Peninsula. In summer, this area is the hottest sea with abundant coral growth on earth and already today exhibits a temperature that is predicted to occur across the topical ocean in 2100. Thus, by studying the Gulf today, much can be learned about tomorrow’s world and the capability of coral reefs to adapt to climatic extremes. This volume provides the most authoritative and up-to-date review of the coral reefs in the Gulf. It can be used as a volume of general reference or as a textbook treating recent coral reefs. Written by local and international experts, the text is richly illustrated and will remain a standard reference for the region for decades to come. Contributions stretch from climatology through geology, biology, ecological modelling and fisheries science to practical conservation aspects. The book is useful for the technical expert and casual reader alike.

Download or read book HS Codes for fisheries and aquaculture products written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2023-06-29 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication, developed by the Food and Agriculture Organization of the United Nations (FAO), with the active support of the World Customs Organization (WCO), builds on the Harmonized System: Nomenclature 2022 edition. It presents all possible classifications for fisheries and aquaculture products by species, with a full description of each HS code, to facilitate its use within the fisheries sector, including aquaculture. This publication does not modify the structure of the HS or modify species grouping, as it is an auxiliary tool to facilitate classification and enhance understanding of the HS system from the angle of fisheries and aquaculture products. This publication is divided into three sections: (1) the first section presents all species which are directly referenced in the HS, with commodity codes for all possible classifications of their products and treatments; (2) the second section lists all HS codes for fisheries and aquaculture products with an exhaustive and comprehensive description of each code; and (3) the third section is a new section of the HS Handbook, where photos of the most commercially important species are shown. Each image contains relevant information and singularities of each species – scientific name, FAO names, main characteristics, and distribution.
